US Patent:

7466100, Dec 16, 2008

Filed:

Jan 17, 2005

Appl. No.:

11/037427

Inventors:

Peter W. Mueller - Ann Arbor MI, US
Jack M. Leason - Royal Oak MI, US

Assignee:

Peaktronics, Inc. - Royal Oak MI

International Classification:

G05B 11/28

US Classification:

318599, 318811, 318471, 318432

Abstract:

Kinematic control of an electronic positioner and its associated actuator is effected through a control algorithm that delivers energy to the actuator based on observed motion produced by a previous delivery of energy. The algorithm achieves control based on a desired or user-specified resolution. Electronic braking between energy delivery intervals improves the speed at which the desired position is achieved. Temperature of the force producing mechanism is determined, as by monitoring energy consumed, and used to control how power is delivered to the actuator.

International Classification:

H04Q 100

US Classification:

3408255

Abstract:

The communications system uses a master line, a slave line and at least one call line to effect true asynchronous communication. A protocol is established whereby a master unit takes control of the call line when the master line and slave line are at the same logical state. The slave unit has control of the call line when the master line and slave line are at different logical states. The system includes an interchange device which routes communications signals in accordance with channel identification commands sent over the communications system. The communications scheme can be implemented on a wide variety of digital communicating devices through the use of a universal command instruction set which provides the data manipulation functions required by most microprocessors.
